We investigate the bit-error rate (BER) of the considered system using multiple relays by considering the effect of Weibull fading parameter and Rician <em>K</em> factor on the system performance. Our simulation results demonstrate the positive impacts of the value of fading parameter, Rician <em>K</em> factor and increasing number of relay nodes on BER performance. It is also confirmed that the Rician <em>K</em> factor is more effective on the system performance over Rician/Rayleigh fading channels in comparison with Rayleigh/Rician fading environment.</span><p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.22.1.14116">http://dx.doi.org/10.5755/j01.eee.22.1.14116</a></p>}, number={1}, journal={Elektronika ir Elektrotechnika}, author={Kapucu, Nuri and Bilim, Mehmet and Develi, Ibrahim}, year={2016}, month={Feb.}, pages={97-101} }
